Hello, everyone. I want to share something about myself with you first. Looking back on my younger days, I find it incredibly ironic how much of my life I spent listening to Pink Floyd, whose hit song Time is specifically about not sitting around and letting life pass you by.
    But, like so many high school and college students, I wasted a lot of my time in the short-and long-term. I would sleep late on Saturdays, lose hours "hanging out" with friends and scrolling through Facebook and Tumblr endlessly.
    In the long-term, I also was never sure what I wanted to do with my life, so I drifted through the easiest college courses, never really pushing myself to do better. It wasn’t until I hit around 25 that I realized I’d missed a large chunk of my life for absolutely no reason. The "good times" I’d had weren’t that great, and, in truth, I was always just passing time until something better came along.
    What I realized is that nothing simply "comes along. " Life is what you make of it. If you’re unhappy with something in your life, there is nothing stopping you from making moves to change it.
    My problem in college was that I’d figured I’d already sunk time and money into studying toward one degree, so switching majors in the middle of my college career would be a hassle. Well, it would have been a minor hassle then, but it’s a major hassle now that I’m in the real world without a clue of where to go from here.
    The idea that good things come to those who wait works for children who rely on their parents for everything they desire in life. Once you have control of your own life, you need to go out and earn everything you desire and hope for in the world.
    You’ll certainly need to be patient, such as when waiting for a call back after an interview, but you shouldn’t waste the time in-between just waiting for your phone to ring.
    I’m not saying you should do the whole " YOLO" thing kids talk about these days and put yourself in danger. But you definitely should take the leaps of faith that are necessary to push you forward in life.
    If you never step out of your comfort zone, you’ll end up sitting on your couch watching sitcom reruns your entire life. Try to do something that scares you and makes you feel vulnerable every day.
    There’s no point in getting out of bed today if you’re going to do the exact same thing you did yesterday. The world has a lot to offer; try to get as much out of it as you can. Wish you save every second of the day. Thanks for listening!
